IPC: D06F33/02
Filed: 2008-04-22
Abstract: <P>PROBLEM TO BE SOLVED: To execute a "dewatering shower rinsing" course, effective for water saving, without generating abnormal vibration.  <P>SOLUTION: In a rinsing step for rinsing the laundry, water is fed to a prescribed level by a water supply pump for feeding bath water into a water tub (S12 and S13), and after that, bath water is circulated and jetted by a circulation pump (S15 and S19). Then, a drum is rotated at low speed while circulating and jetting bath water (S20 and S21). In this way, bath water is circulated and jetted by the circulation pump and is sprayed to the laundry on the upper layer before the start of rotation of the drum after water feeding in the rinsing step. Accordingly, the fed water is absorbed in the whole laundry from the laundry on the lower layer to the laundry on the upper layer, and there is no difference in the weight between the laundry on the lower layer and the laundry on the upper layer. As a result, unbalance of the loads does not occur even if the rotation of the drum is started thereafter, and generation of abnormal vibration can be prevented.  <P>COPYRIGHT: (C)2010,JPO&INPIT
